However, the diplomat expressed concerns about the different reactions by the parties to the deal when to the U.S. withdrew from the pact in 2018 and when Iran took its reciprocal steps a year later.
Iran says it welcomes France's efforts to ease the tensions recently raised over the 2015 nuclear deal and contribute to preserving the deal, which has been challenged by the US.
Diplomats from several countries on the IAEA board said that while fiery exchanges between the Iranian and U.S. envoys were likely at the meeting at agency headquarters, they did not expect the board to take any concrete action.
"Iran has always been secretly 'enriching, ' in total violation of the bad 150 Billion Dollar deal made by John Kerry and the Obama Administration".
The multilateral pact saw Iran accept drastic limits on its nuclear programme and to submit to IAEA inspections in exchange for a partial lifting of crippling global sanctions.
"There is no credible reason for Iran to expand its nuclear program, and there is no way to read this as anything other than a crude and transparent attempt to extort payments from the worldwide community", the USA statement to an emergency global Atomic Energy Agency board meeting said.
Tehran has threatened to ramp up uranium enrichment to 20 per cent purity, with the UN's nuclear watchdog confirming it has already passed a limit agreed in a 2015 nuclear deal.
Kazim Gharib Abadi, Iran's ambassador to the IAEA, told reporters following Trump's accusation that all Teheran's nuclear activities were being monitored by IAEA inspectors.

On top of that, other small features like the IR Motion Camera and HD Rumble have been removed as well. The Switch Lite also doesn't have a kickstand, so it can't be used in tabletop mode either.
Rouhani told Bonne Iran seeks "full implementation" of commitments from all parties to the agreement, and "if signatories to the deal implement their commitments, Iran also will take new steps", according to Rouhani's website.
Meanwhile, the USA special representative for Iran, Brian Hook, told Al Arabiya that Iran has rejected diplomacy "too many times", and that "right now, there are no back-channel talks between the United States and Iran".
Iranian President Hassan Rouhani called it a "sad irony" that an International Atomic Energy Agency meeting is being held at the behest of the USA despite President Trump being the main contributor to the demise of the Iran deal. "Under global control, it poses no risks for non-proliferation", the ambassador said in a Twitter post.
Wolcott reiterated that Washington believes the deal was ineffective, but remains "open to negotiation without preconditions".
Iranian news agency IRNA also quoted Mousavi as saying that he has heard about the "freeze against freeze" plan but did not elaborate.
The US and the European countries are deceiving us.
The other parties in the deal - Russia, China, Germany, France, Britain and the European Union - have called for Iran to stick to its commitments.
The measures are in response to the US' withdrawal and Europe's failure to comply with its own JCPOA commitments regarding Iran's economic interests.
Ulyanov pointed out that the nuclear deal's goal was not only to resolve nuclear issues but to normalise economic and trade relations with Iran, as sanctions were to be lifted gradually in exchange for Tehran keeping its nuclear program peaceful. He warns London: "You are an initiator of insecurity and you will understand its repercussions", without elaborating.
